Cevap

Theory of Absolute Advantage matches with Adam Smith's principle of lower total resource input; Theory of Comparative Advantage matches with David Ricardo's relative opportunity cost model; Opportunity Cost Approach matches with Gottfried Haberler's PPC reformulation; Limits of Mutually Beneficial Terms of Trade matches with the range bounded by domestic opportunity cost ratios.

Each trade theory is paired correctly with its seminal economist and core principle: Adam Smith with absolute resource efficiency, David Ricardo with relative opportunity cost, Gottfried Haberler with the PPC opportunity cost reformulation, and terms of trade bounds with internal domestic ratio limits.

Adım Adım Çözüm

1

Identify the primary author and principle behind classical absolute advantage.

Adam Smith proposed absolute advantage based on producing more output per unit of resource.

This establishes the historical foundation of free trade theory based on absolute cost superiority.

2

Differentiate Ricardian comparative advantage from absolute advantage.

David Ricardo showed that relative opportunity cost determines specialization and trade gains.

Even if one country has an absolute advantage in all goods, trade remains beneficial based on relative cost differences.

3

Associate the opportunity cost refinement with its proponent.

Gottfried Haberler substituted the rigid labor theory of value with opportunity cost concepts.

This allowed trade theory to account for multiple factors of production using marginal analysis.

4

Determine the conditions for equilibrium terms of trade.

The terms of trade must lie between the domestic cost ratios of both trading partners.

If terms of trade fall outside these bounds, at least one nation would be worse off trading than remaining self-sufficient.

Soldaki öğeye tıklayın, sonra eşleşen sağdaki öğeye tıklayın

Cevabı ve açıklamayı göster

Cevap

The correct pairings match each biological indicator or control intervention to its specific ecological purpose: agricultural lime neutralizes water acidity from acid precipitation; high BOD quantifies organic sewage pollution; lichen diversity measures air quality and sulfur dioxide levels; and specialized Pseudomonas bacteria perform bioremediation of crude oil spills.

Each monitoring technique or control method directly corresponds to its established ecological application: agricultural liming neutralizes acid rain effects; BOD measures organic sewage pollution; lichen bio-monitoring detects sulfur dioxide air pollution; and hydrocarbon-degrading bacteria perform oil spill bioremediation.

Adım Adım Çözüm

1

Analyze the chemical control technique: application of agricultural lime.

Liming adds calcium carbonate (

CaCO_3

) to acidic aquatic bodies to neutralize excess hydrogen ions produced by acid deposition.

Acid rain lowers aquatic pH, which liming directly counteracts to restore ecological balance.

2

Evaluate the water quality parameter: Biological Oxygen Demand (BOD).

BOD measures the rate of oxygen consumption by aerobic microorganisms breaking down organic matter in water.

Elevated BOD levels directly reflect heavy organic pollution, such as untreated domestic sewage, which depletes dissolved oxygen.

3

Identify the ecological bio-indicator role of epiphytic lichens.

Lichens absorb nutrients directly from the atmosphere and are highly vulnerable to toxic gases like sulfur dioxide (

SO_2

).

Monitoring lichen species distribution provides an effective biological measure of atmospheric air pollution.

4

Examine the biological remediation mechanism of Pseudomonas bacteria.

Certain Pseudomonas strains utilize petroleum hydrocarbons as a carbon source, converting toxic oil constituents into biomass, carbon dioxide, and water.

This process represents targeted bioremediation of marine and coastal oil spills.

Cevap

State pensions and unemployment relief grants match with Transfer payment (Excluded from National Income); Dividends distributed to shareholders match with Corporate profit component; Net income earned by a sole proprietor matches with Mixed income of the self-employed; Royalties received by a landowner match with Rental income.

The income method measures national income by summing all factor rewards earned by residents for participating in current economic production: compensation of employees (wages/salaries), rental income (including land royalties), net interest, corporate profits (dividends, retained earnings, tax), and mixed income of the self-employed. Receipts that do not correspond to productive output, such as welfare grants and pensions, are transfer payments and are strictly excluded.

Adım Adım Çözüm

1

Identify non-factor payments that do not reflect current economic output.

Unemployment grants and state pensions are non-factor receipts (transfer payments) and must be excluded from Gross Domestic Product under the income approach.

Including transfer payments leads to double counting, as no productive activity occurred in exchange for the payment during the current accounting period.

2

Each factor of production contributes a specific economic role and receives a designated type of return: Land earns Rent due to its fixed natural availability; Labour receives Wages for human productive effort; Capital earns Interest as a return on accumulated wealth used for production; and Entrepreneurship receives Profit as a residual return for decision-making and risk-taking.

Adım Adım Çözüm

Identify the reward and characteristics of Land

Land is a primary, free gift of nature with fixed supply that receives Rent.

Land cannot be expanded in total quantity by human effort.

Labour represents human mental or physical effort paid via Wages or Salaries.

Labour is inseparable from the worker.

3

Identify the reward and characteristics of Capital

Capital represents man-made assets created for further wealth creation, receiving Interest.

Capital depreciates over time and is accumulated through saving and investment.
